The goal of the May drill is to focus on ventilation
Fire Attack: Positive Pressure
- What is the purpose of Positive Pressure Ventilation (“PPV”)?
- What are the variables of the environment and structure that need to be considered in utilizing a coordinated PPV attack.
- What are the risks associated with PPV?
- What is the proper positioning of a fan for PPV? (4 to 6 feet back, angled back 5 to 15 degrees)
- How large does the exit vent opening have to be in relation to opening the utilized by the fan for PPV? (2x time size plus)
- Remember – always coordinate any PPV with the Incident Commander due to its impact on fire/smoke and heat conditions inside the structure.
Training Minutes: Roof Access
Reality Training: Vertical ventilation
- What tools/equipment is needed before ascending ladder to roof, and what needs to be confirmed?
- How do you ensure that the roof is sound, and when is a roof ladder needed?
- Where/How is inspection cut made, and what is purpose?
- After any hole is cut and roof opened, what does the 2nd FF do (the pole FF)?
- Reminder – never block off your path of egress from the roof.
- How do you perform hydraulic ventilation with a smooth bore nozzle vs. a fog or combination nozzle?
- How much of opening are we looking to cover with the hose stream for effective hydraulic ventilation?
- In what stage should the fire be when initiating hydraulic ventilation?
